2️⃣ Ternary Operator
Checks a condition and executes the first expression if the condition is true. Otherwise it runs the second expression.

3️⃣ Jump / Dispatch Table
Stores value-function pairs in an object to quickly fetch and run a function based on a value (which is treated as an object key).

4️⃣ Dynamic Dispatch
This pattern involves selecting which polymorphic method to call based on an object’s type.
